I added 3 lbs. of stabilizer snd it's almost dissolved. That's what it said to bring the cya up the 20ppm that I needed. I tested the cya and I still can see the black dot but it's blurry when the tube is completely filled so I'm thinking it's maybe around 10ppm. The alkalinity is 100, ph7.5 abs free chlorine 3, cc .5 so total chlorine 3.5. Should I add two or three strikes of shock tonight and see what the level is tomorrow? If my cya isn't high enough adding the shock is not going to help so should I add what I hsve left, which is 1lb., to the skimmer to bring it up? Thank you.
